SLEEPIN G-CAR.

SPECIFICATION forming part of Letters Patent No. 236,445, dated January11, 1881.

Application filed November 22, 1880.

To all whom it may concern:

Be it known that I, CHRIsrrAN E. LUcAs, of Atlanta, in the State ofGeorgia, have invented certain new and useful Improvements in theConstruction of Sleeping-Cars; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawing,and to letters of reference marked thereon, which form a part of thisspecification.

The drawing represents a vertical cross-section of a sleeping-car havingmy im proved. construction.

Corresponding parts on the two sides ofthe car are indicated by similarletters of reference.

My invention relates to the construction of the upper berth and framingof the car, and has for its object to improve the "entilation of the carand berth, and to give a more lofty car.

The invention consists in the location of an air-chamber provided withsuitable inlet and outlet Ventilating-apertures between the main roof ofthe car and its ceiling and above the upper berth, and in giving to theinner face of said chamber and to the lower side of the berth a peculiarinclination and curvature, both sa-id parts uniting in the formation ofa single unbroken springing curved line beginning at the molding whichsupports the lower edge ofthe berth and terminating in the clearstory ofthe car, all as hereinafter more specifically set forth.

In the accompanying drawing, E marks the floor of the car; S S, itssides; R, the main roof, and It the roof of the clear-story.

Under the roof R, 1 form an air-chamber, A, having the shape shown, andprovided with the air-inlet a, which admits the outer air, theair-passage b, which connects the air-chainber C, and the outlet c,which opens just below the mouth d of an exhaust-ventilator, V, attachedto the side of the clear-story. Iprefer to lmake this ventilator of thekind de- (No model.)

scribed in my Patent No. 220,628; but any efcientexhausting-ventilatorwill serve the purpose of my present device.

The berth B is supported at its lower edge, c, on the molding M, or inany usual manner. It is about two inches deep at the point e and aboutseven inches deep at its upper edge, f, and provided with end pieces ofsuitable form. The line of the face of the berth from e to f inclinestoward the middle of the car, as shown, and forms a continuous springingcurve with the linej'g of the face of the chamber A. By this inwardinclination of line c f and its production to g, I obtain the necessaryspace in the upper angle ot' the car for the location of theair-chamber, and for the accommodation of the bedding when the berth isclosed.

When in use the berth occupies the positioii shown in dotted lilies inthe drawing.

The effect of the construction is, that air enters from without at theinlet a, passes through the air chamber A, and escapes through outlets cand d and the exhaustingventilator V at the top of the car. An iiiducedcurrent ilowing through b carries off the vitiated air from the upperberth, While its occupant is entirely protected from the external draft.

When the berth is closed the Ventilating arrangement secures the generalventilation of the car in the saine advantageous manner, and also tendsto air and keep dry the bedding stored in the space C.

rIhe ornamental effect of the upward-spriii ging curve c g upon theappearance ot' the interior of the car is obvious upon inspection.

What I claim, and desire to secure by Letters Patent, is-

l. The berth B, having the curved face ef, in combination with thechamber' A, having the similarly-curved face f g, both constructed andarranged substantially as described, for the purpose set forth.

2. The combination, with a railway-car, ot' an air-chamber locatedbeneath the main roof on either side, as shown, and cominuuicating withthe outer air and the interior of the car by inlet and outlet aperturesand an eX- hausting-ventlator, all substantially in the In testimonythat I claim the foregoing as manner and for the purpose specified. myown invention I affix my signature in pres- 3.
